Geometridae 

By D. S. Fletcher 
British Museum (Natural History) 

The Geometridae collected during the British Museum expedition to East Africa in 1934-5 and 
during the expedition to Ruwenzori in 1952 together consist of 1407 specimens representing 
239 species and subspecies, of which 76 proved to be new to science. Seven have already been 
described elsewhere and 69 are described in the following pages. Of the 239 species collected, 
182 are from Ruwenzori and 57 from various localities in Kenya and Uganda visited by the two 
expeditions. Certain additional material from the unnamed accessions in the British Museum 
and specimens collected by A. Holm during the Swedish expedition to the mountains of East 
Africa in 1948 and kindly loaned by Dr. Rene Malaise of the Riksmuseum in Stockholm have 
also been included in this paper. 

As already stated in the general introduction to this series, the pattern of collecting on Ruwen- 
zori during the 1952 expedition followed closely the different vegetation belts found on the 
mountain; the following specific lists illustrate the marked differences found in the Geometrid 
faunas of these successive belts, especially in the distribution of the subfamilies. It will be seen also 
from these lists and from the distribution table that follows them, that the species occurring in 
the savannah and the partially cultivated elephant grass belts are largely of the subfamilies Sterr- 
hinae and Ennominae and, as one would expect, have a wide distribution both to the east and to 
the west of Ruwenzori. For this reason, very little time was devoted to collecting in the savannah 
and the species listed from that region are few. 

In the montane rain forest, immensely rich in species though sparse in individuals, the number 
of species having a wide distribution is proportionately lower and a number of species occur 
there that are so far recorded only from the Western Rift Valley. 

The bamboo belt, which hes between the montane rain forest and the ericaceous belts, appears 
to be a most effective ecological barrier, for there are only four species of Geometridae known 
to occur on both sides of it. Apart from one species of Sterrhinae, Scapula latimediata sp.n., all 
the species of Geometridae occurring above the bamboo belt belong to the subfamily Larentiinae. 
The occurrence here of two species of the genus Haplolabida gen.n. is of interest; both are repre- 
sented by subspecies on Mount Kilimandjaro on the eastern side of the Eastern Rift Valley; the 
other species in the genus occur in S. Africa. Apart from these and Eupithecia dohertyi Prout and 
from Eupithecia proflua suhvincta Prout, recorded previously only from the Aberdare Range in 
Kenya, the distribution of those species occurring in the ericaceous belt is confined to the Western 
Rift Valley. 

The only species of Geometridae occurring in the alpine belt are the remarkably abundant,

nocturnal Xanthorhoe alluaudi hancocki Prout, the diurnal species X. w. welhi Prout, X. wellsi 
capnoessa subsp.n., X heteromorpha albicera subsp.n. and X. /;. heteromorpha Hampson; these species 
have brachypterous females, as do their relatives in the ericaceous belt, X. barnsi Prout and X. a. 
alluaudi Prout, and may prove to be endemic. 

The colour names used in the descriptions of the new species are taken from Ridgway's Color 
Standards and Color Nomenclature. Below each previously described species is given its known 
distribution up to the time this paper was prepared. All specimens, unless otherwise indicated, 
are in the British Museum.

Examination of the genitalia of the types of P. scissaria Felder (1875), P. unipuncta Warren (1897) 
and P. degenerata Prout has shown them to be identical. Specimens from Abyssinia to Tanganyika 
have a white spot edged distally with fuscous at the middle of the inner margin of the fore wing; 
for this subspecies the name degenerata Prout is available. The nominate subspecies, which occurs 
from S. Rhodesia to the Cape, has the fore wing uniformly green. Among the nominate sub- 
species occasional specimens occur, which are marked similarly to s. degenerata; for these aberra- 
tions the name unipuncta Warren is available.

Prasinocyma caecata sp.n. (Figures 91-93) 

o* 40 mm.: Palpus white beneath, vinaceous above, equal in length to three-quarters of diameter 
of eye; third segment minute. Antennal shaft, head and collar white. Frons, thorax, abdomen 
and upperside of wings pale olivine, the latter striate with white. Cell spots minute on both 
wings, fuscous. Underside of wings whitish. FLind tibia dilate with hair pencil. 

Genitalia: Uncus simple, little longer than the apex of the gnathus, which is produced narrowly. 
Basal two-thirds of ventral margin of valve lightly sclerotized; a sclerotized band extends diagon- 
ally across valve from dorsal to ventral margin, as figured. Aedeagus narrowly rounded at base 
and apex. Vesica with five cornuti as figured. Eighth sternum with two triangular projections 
from posterior edge. 

Related to P. pupillata Warren (1902) but lacking the conspicuously large cell marks of that 
species. In the male genitalia of pupillata the sclerotized band on the valve is densely but minutely 
scobinate and the vesica bears only three cornuti.

Prasinocyma simpliciata sp.n. (Figures 100, 101) 

o* 34 mm. : Palpus vinaceous, equal in length to diameter of eye. Frons pale pinkish buff. Head, 
collar and abdomen dark greenish glaucous mixed with white. Thorax and upper surface of 
wings dark greenish glaucous, the latter striate with white. Fore wing with costa narrowly pinkish 
buff and a black spot at middle of inner margin. Cell spots on both wings black. Fringes con- 
colorous with wings. Underside. Fore wing marked similarly to upperside, costa and proximal 
half of subcostal vein pinkish buff mixed with fuscous. Flind wing paler. Cell spots wanting. 
The fringes are marked with a fuscous spot at the end of each vein. Hind tibia dilate and bearing 
a hair pencil. 

Genitalia: Uncus simple and of even width, bluntly tipped. Gnathus produced, subequal to 
uncus. Basal three-fourths of ventral margin of valve lightly sclerotized, broadly basad, narrowly 
apicad, with a triangular process arising from inner edge near base; a lightly sclerotized band 
extends diagonally from mid-base to tip of ventral margin. Basal third of aedeagus one-fourth 
as wide as remainder; vesica with two small, tapered cornuti. Eighth sternum simple. 

Related to P. pupillata Warren (1902) and to the preceding species; as with other species in the 
genus, most reliably determined by the structure of the genitalia. The straight, posterior edge 
of the eighth sternum of P. simpliciata, which may be studied without dissection, at once dis- 
tinguishes it from its closest relatives.

Distribution: S. Sudan; Kenya. 

Prasinocyma corrugata sp.n. (Figures 94-96) 

J 36 mm.: Palpus white beneath, rivage green above, equal in length to diameter of eye. Lower 
part of frons white, upper part rivage green. Head and thorax deep glaucous green mixed with 
white. Wings deep glaucous green, smooth scaled and lightly striate with white. Costa of fore 
wing narrowly white. Fringes white, edged proximally with deep glaucous green and distally 
with fuscous. Cell spots fuscous ringed with white. A white spot at middle of inner margin of 
fore wing is edged distally with fuscous. Underside whitish and glossy. Hind wing angled at 
vein M3. Hind tibia dilate and bearing a hair pencil. 

Genitalia: Uncus stout and tapered, subequal to apex of gnathus, which is produced and scoop- 
shaped. Basal three-fourths of ventral margin of valve lightly sclerotized, narrowly towards 
apex, broadly with corrugations towards base. A slender, lightly sclerotized band extends 
diagonally across valve from middle to just beyond ventral margin; the projecting part is strongly 
scobinate. Basal half of aedeagus narrowed to one-fifth of apical half; vesica with three tapered 
cornuti. Eighth sternum shaped as illustrated. 

Related to the preceding species, from which it is best distinguished by the genitalia. 

kenya: Aberdare Range, Mt. Kinangop, 8000 ft., x.1934 (Edwards), 1 holotype. 

Prasinocyma trifilifimbria uniformata subsp.n. (Figures 102-104) 

Differs slightly from t. trifilifimbria Prout (191 5) in the structure of the male genitalia and super- 
ficially in the colour of the fringes. In the nominate subspecies the fringes are white edged 
proximally with glaucous green and distally with fuscous; in subspecies uniformata the fringes are 
concolorous with the wings, glaucous green. 

Genitalia: Apex of valve broadly rounded with a narrow, tapered, sclerotized area extending 
parallel with the ventral margin; harpe on ventral margin of valve incurved at apex with rounded 
tip. In the nominate subspecies the apex of the valve is narrowly rounded and the harpe is similarly 
incurved but tapered to a sharp point. The differences in the aedeagi and eighth sterna are shown 
in the figures (Figures 105, 106). 

kenya: Aberdare Range, Mt. Kinangop, 8000 ft., x.1934 (Edwards), 1 holotype. 

Prasinocyma crenulata sp.n. (Figures 97-99) 

40 mm.: Palpus white beneath, vinaceous above, slightly longer than diameter of eye. Frons 
white with some green scaling near head. Head, thorax and abdomen white mixed with deep

Geomctridae 85 

Genitalia: Uncus simple, apex rounded. Apex of gnathus semicircular. Juxta almost rectangular, 
apex truncate. Harpe on ventral margin of valve incurved at apex as in trifilifimbria Prout (1915). 
Basal third of aedeagus narrowed to one-fourth; apical half sclerotized at one side; vesica with 
three cornuti as figured. Posterior edge of eighth sternum sclerotized and crenulate. 

Similar in colour to the preceding species and closely related to it; differs superficially in the 
presence of a large white spot at middle of inner margin of fore wing, the spot not being edged 
distally with fuscous, and the much reduced fuscous cell spots; differs structurally in the male 
genitalia (Figures 97-99).

40 mm.: Superficially closely similar to the preceding species, differing only in the larger 
fuscous black cell spots and in the spot at middle of inner margin of fore wing, which is white 
edged distally with fuscous black. 

Genitalia: Uncus similar to that of crenulata. Apex of gnathus rectangular. Apex of juxta 
strongly bilobed. Valve and shape of aedeagus similar to those of crenulata. Vesica with a sinuous, 
sclerotized band, a broad-based cornutus tapered sharply at one side apicad and four small, 
sclerotized plates. Posterior margin of eighth sternum with two triangular projections.

twice as long as diameter of eye. Frons, head, thorax and abdomen glaucous green mixed with 
white. Upper surface of wings glaucous green striate with white. Cell spots minute, indicated 
only by a little denser green scaling. Underside whitish. Costal vein on fore wing pinkish buff 
above and beneath, riind tibia of male dilate with a hair pencil. 

Male genitalia : Uncus simple, twice as long as the slenderly produced apex of the gnathus. A 
slender, sinuous, sclerotized ridge extends along centre of valve from base to two-thirds; harpe 
on ventral margin of valve slender, incurved and lightly serrate. Aedeagus broad at middle, 
tapered apicad; basal third reduced to one-fifth of greatest width. Vesica with two tapered 
cornuti, one one-half and one one-third as long as the aedeagus. Eighth sternum shaped as 
illustrated. 

Female genitalia: Genital plate sclerotized and shaped as illustrated. Ductus bursae short and 
partially membranous. Bursa copulatrix membranous and ovate with a single two-spined signum. 

Similar, in the almost complete lack of pattern, to P. ampla Warren (1904) but readily dis- 
tinguishable from that and other species in the genus by the genitalia (Figures 109-112).

Prasinocyma edwardsi sp.n. (Figures 113-116) 

0*$ 40 mm. : Palpus white beneath, vinaceous above, equal in length to diameter of eye in both 
sexes. Frons vinaceous. Head, thorax and abdomen deep lichen green mixed with white. Wings 
deep lichen green irrorate with white. Cell spots minute, of a darker shade of green. Fringes 
concolorous with wings. Flind tibia of male not dilate and without hair pencil. 

Male genitalia : Uncus stout, apex broadly rounded. Apex of gnathus produced and tapered. 
Valve with a slender weakly sclerotized area parallel with ventral margin ; a weakly sclerotized 
harpe with tapered apex, extends to three-fourths ventral margin. A tapered, sclerotized process 
arises from one-half ventral margin, extends towards base of valve, curves sharply towards dorsal 
margin and then extends diagonally across valve towards apex of harpe. Basal third of aedeagus 
narrowed to one-third of width of remainder ; apical half sclerotized at sides, one of which is 
scobinate. Vesica without cornuti. Eighth sternum shaped as illustrated. 

Female genitalia: Genital plate shaped as illustrated, with two sclerotized ridges extending 
posteriorly from anterior edge. Bursa copulatrix pyriform and membranous with a single 
si gnu m. 

The species is closely related to P. tricolorifrous Prout (1913), now transferred from Hemistola 
on the basis of the structure of the genitalia, but differs from it superficially in the more acute 
apex to the fore wing and structurally in the tapered harpe and more slender uncus ; in tricolorifrous 
the apex of the harpe is broadly rounded and that of the uncus broadly spatulate.

Comparison of the male genitalia of C. attenuata Walker (1862) and C. eborilitoris has shown the 
two to be distinct species. In attenuata the tapered process arising from the mid-dorsal margin 
of the valve is one-third as long as the socii; in eborilitoris it is two-thirds as long. In attenuata an 
anteriorly curved, scobinate process arises from the mid-ventral margin of the valve and is more 
than twice as long as the socii; in eborilitoris this process is straight and shorter than the socii.

Cosmostolopsis simplex rubropunctata subsp.n. 

In structure apparently identical with s. simplex Warren (1902) but differing superficially in having 
a red frons and three red spots on the otherwise white transverse fasciae of each wing. On the 
fore wing there is one spot on the antemedial fascia at the inner margin and two on the post- 
medial fascia, one at vein M3 and one at the inner margin, with sometimes a third on vein Mi. 
On the hind wing there are three spots on the postmedial fascia, one each on veins Mi and M3

upper part of frons fuscous black. Thorax and abdomen light buff, abdomen with a few scattered, 
fuscous scales. Wings light buff suffused distally, and on the fore wing costally, with tilleul buff 
and very lightly irrorate with fuscous. Antemedial and medial fasciae weakly marked; post- 
medial fascia dentate, strongly marked between vein Cr/2 and inner margin on fore wing, other- 
wise represented by spots on the veins; all fuscous. Terminal interneural spots fuscous. Fringes 
concolorous with wings and spotted with fuscous at vein ends. Cell spots fuscous, clearly marked. 
Underside light buff and glossy, fore wing suffused with fuscous, more strongly towards costa.

strongly fuscous. 

Genitalia: Socii twice as long as the membranous dorsal lobe of valve; ventral arms of valves 
sclerotized, tapered and symmetrical. Aedeagus shaped as figured; vesica with one flat, almost 
rectangular cornutus. Mappa and cerata shaped as figured. 

Closely related to the preceding species, differing from it superficially in the ground colour of 
the wings and the shape of the postmedial fascia on the fore wing. Differs structurally in the 
cerata; in candidaria the right arm is two-thirds as long as the left and incurved apically ; in calcarata 
the right arm is one-fourth as long as the left and straight.

white very lightly irrorate with fuscous. Wings, proximad of postmedial fasciae, white, costal 
area lightly irrorate with fuscous. Medial fascia of fore wing marked only by a fuscous spot at 
two-thirds costa. Cell spots on both wings fuscous. Distad of postmedial fasciae the wings arc 
suffused with fuscous and fuscous black. Underside similar to upperside, but the fuscous markings 
are very much weaker. 

Genitalia: Ostium bursae shaped as shown in figure. Genital plate semicircular and of even 
width. Ductus bursae membranous, rather more than one-third as long as the ovate bursa copula- 
i trix, which is membranous and patterned with small, broad-based spines as figured. Distinguished 
; from other species in the Pylarge sections of Scopula by the very distinctive pattern of the wings 
and by the structure of the genitalia (Figure 61).

black. Antemcdial fascia on fore wing almost semicircular, extending from radius to submedian 
fold, being marked with dashes on radius and cubitus. Medial fasciae on both wings broad and 
ill-defmed; postmedial fasciae dentate, marked strongly on veins, especially on fore wing. 
Terminal interneural spots fuscous black. Fringes pinkish buff with fuscous spots at vein ends.

strongly suffused with fuscous black. Postmedial fascia on fore wing strongly marked from costa 
to submedian fold. Postmedial fascia on hind wing entire but weakly marked. Cell spots as on 
uppcrsidc. 

In three examples both wings are densely irrorate with fuscous black; apart from the cell spots, 
the markings are scarcely traceable.

larger on the left side than on the right. Aedeagus slender and tapered apicad; vesica with one 
cornutus, a short, inverted spine. Mappa and cerata as figured. 

Differs from the closely related S. tnacronephes, of which it might prove to be the male, in 
pattern but similar in size and wing-shape and, on that account, conspicuous in the Pylarge 
section of Scopula.

The specimens from Fort Portal and Kilembe (wing-span 24-26 mm.) are suffused with dull 
ochraceous; two other specimens from Uganda in the British Museum are similarly coloured. 
The specimens from Ibanda (wing-span 20 mm.) are smaller, paler and the usually well con- 
trasted subterminal fascia and terminal area are but poorly defined; perhaps an arid-country form. 

5. clisabetliae Prout (1934) and 5. obliquisignata Bastelberger (1909) differ structurally from 
caducaria only in the cerata; in elisabethae the cerata are of equal length and slightly incurved 
apicad; in obliquisignata the left ceratum is two-thirds as long as that on the right; in caducaria 
the right ceratum is one-half as long as that on the left and incurved almost from its base. 

Scopula lugubriata sp.n. (Figures 3, 60, 62, 128, 129) 

^ 26-30 mm.; $ 24-28 mm.: Male antenna ciliate; hind tibia three times as long as tarsus and 
dilate with hair pencil. Inner surface of palpus and lower part of frons light buff; outer surface 
of palpus and upper part of frons fuscous black. Wings pinkish buff proximad of postmedial 
fascia ; distad of it, light vinaceous cinnamon divided by a lunulate subterminal fascia of pinkish 
buff; the whole lightly irrorate with fuscous. The three transverse fasciae are weakly marked in 
light vinaceous cinnamon, the postmedial being the most distinct. Cell spots minute, fuscous. 
Fringes pinkish buff irrorate with fuscous. Underside glossy, light buft; anterior half of fore wing 
suffused with fuscous. Cell spots and medial fasciae on both wings and postmedial fascia on fore 
wing fuscous, weakly marked. 

Male genitalia: Socii as long as membranous dorsal arms of valves, which are bifid. Ventral 
arms of valves tapered apicad and symmetrical. Anellus lobes narrowly rounded apically. 
Aedeagus tapered apicad, narrowed medially; vesica with two weak cornuti medially and a 
third, smaller one in basal fourth. Mappa and cerata as figured. 

Female genitalia : Ostium bursae broad posteriorly, narrowed anteriorly, as long as the mem- 
branous ductus bursae. Bursa copulatrix pyriform and ornamented as shown in figure. 

Closely related to S. internata Guenee (1858), from which it is best distinguished by the genitalia 
(Figures 60, 62, 128, 129) ; those o£ internata are figured by Janse, 1934, Moths S. Africa, 2, Figures

Ab. limosata ab.n. (Figure 8). 

The specimen from the Mahoma River, though agreeing in structure with i. internata Guenee 
(1858) and i. praeruptorum, is very different in appearance. The wings are pale pinkish buff lightly 
irrorate with fuscous black; the fore wing has three and the hind wing two sharply defined, 
fuscous black, transverse fasciae, as shown in the figure. Termen fuscous black. Fringes pinkish 
buff. Cell spot on fore wing is situate just proximad of medial fascia. Underside glossy, pale 
pinkish buff; fore wing lightly suffused with fuscous proximally. Medial and postmedial fasciae 
and termen marked as on upperside. 

Scopula incalcarata sp.n. (Figures 6, 135, 136) 

$ 26-29 mm. : Antenna ciliate. Hind tibia three times as long as tarsus, without spurs and dilate 
with hair pencil. In colour and pattern closely similar to S. calcarata, described in this paper, but 
with the postmedial fascia on the fore wing not so strongly marked between vein C112 and inner 
margin. 

Genitalia: Socii equal in length to membranous dorsal arms of valves, which are bifid; ventral 
arms symmetrical, tapered and strongly sclerotized. Gnathus wanting. Basal third of aedeagus 
broad, apical third strongly sclerotized and keel-shaped. Vesica with a weakly sclerotized, 
rectangular cornutus near apex. Mappa and ccrata as figured. 

Closely related to 5. internata Guenee (1858) but differing in the structure of the genitalia. In 
internata there is a weakly developed gnathus consisting of two short, tapered arms, one arising 
from the base of each socius. 

The males of S. calcarata and S. incalcarata may be distinguished readily by the differences in 
the structure of their hind tibiae.

Through the courtesy of Dr. Elk Franz of the Senckenberg Museum in Frankfurt a.M., it has 
been possible to study the genitalia of S. tremula Bastelbcrger ; they proved to be conspecific with 
those of internataria Walker. Prout (1935, Lep. Cat., 68:444) had earlier suggested that the 
Bastelbcrger name might be associated with S. minorata Boisduval.

LARENTIINAE 

Xanthorhoe a. alluaudi (Prout) 
Lareutia alluaudi Prout, 1932 (January), Mem. Soc. zool. Fr., 29:429. 

ruwenzori: Nyamaleju, 10,530 ft. (Fletcher) 4 Bigo, 11,400 ft. (Fletcher), 35 ^. 

The type of X. alluaudi was supposed to have been collected at an altitude of 2800-3000 metres 
in the alpine meadows of Mt. Kilimandjaro in 1909 by Alluaud, but there is reason to believe 
that it was in fact collected on Ruwenzori, probably in the Mubuku or Kabwamba valleys. 

Charles Alluaud and his wife collected on Kilimandjaro during the latter part of 1908 and 
before the end of the year had left for Uganda, arriving at Fort Portal on January 7th 1909. The 
early part of 1909 was spent collecting on Ruwenzori and at no time that year did they return 
to Kilimandjaro. 

X. alluaudi is abundant in the ericaceous zone of Ruwenzori but is unknown from any other 
locality. Similarly X heteromorpha Hampson (1909), also supposed to have been collected by 
Alluaud on Kilimandjaro and recorded by Prout (I.e., p. 430), occurs commonly in the ericaceous 
zone of Ruwenzori and is unknown from any other locality; further, the species shows con- 
siderable subspecific differences at different elevations and Alluaud's specimens match well those 
from the type locality. A third species, Eupithccia tricuspis Prout (1932, I.e., p. 443), was described 
from another Alluaud specimen labelled 'Kilimandjaro, alpine meadows, 2800-3000 metres, 
1909'; this is also common in the ericaceous zone of Ruwenzori and unknown from any other 
locality. In the collection of the Paris museum there are two species of Agrotidae, Epipsilia rho- 
dopea Hampson (1907) and Graphania tortirena Prout (1921), both collected by Alluaud and 
labelled Kilimandjaro but occurring commonly in the ericaceous and alpine zones of Ruwenzori 
and unknown from any other locality. 

It would seem reasonable therefore to conclude that an error of labelling has occurred and 
that the type locality of X. alluaudi is the ericaceous zone of Ruwenzori. 

The series from Bigo has a wing-span varying from 31-37 mm. and that of the type, using a 
similar system of measurement, that is, twice the distance from centre of thorax to apex of fore 
wing, is 36 mm. In colour the fore wings are predominantly ochraceous tawny to orange cinna- 
mon irrorate with fuscous, especially in the medial area; the hind wings are light buff. The 
species is night-flying and abundant at light wherever there are growths of shrubby Alchemilla. 
The female is almost certainly brachypterous. 

Distribution: Ruwenzori, ericaceous zone, 10,500-11,500 ft.

Larger than a. alluaudi, having an average wing-span of 40-42 mm.; both wings are suffused 
with fuscous, the fore wing densely, the hind wing to a lesser degree. Some of the specimens

from the Lamia, Nyamgasani and Namwamba Valleys are intermediate in colour between a. 
alluaudi and a. hancocki, but the specimens from above 13,000 ft. are remarkably constant. 

The female is brachypterous ; the much reduced fore wing is tapered distally, the basal and 
medial areas are fuscous black, the remainder being cinnamon to snuff brown irroratc with 
fuscous; the hind wing is rounded distally and drab with a well marked, fuscous, medial fascia. 
Two of the nine specimens were found inside the light trap, one was beaten from Lobelia wollastoni 
Baker and the remaining six were beaten from shrubby Alchemilla, which grows abundantly 
just above Lake Bujuku.

Female unknown, almost certainly brachypterous. 

A day-flying species, which seems to prefer the wetter valleys in the upper ericaceous zone 
of Ruwenzori, the only locality from which the species is known. 

Xanthorhoe heteromorpha albicera subsp.n. 

Differs from the nominate subspecies in the suffusion of the fore wing and especially the hind 
wing with pale to warm buff. Female unknown, almost certainly brachypterous. 

The species flies freely in the sunshine over shrubby Alchemilla in the upper reaches of the 
Bukurungu River, just below Lake Bukurungu; the habitat is considerably drier, being better 
drained than that of h. heteromorpha.

Specimens from the lower elevations are on average rather smaller in size. The species flies 
freely in the sunshine wherever there are ample growths of shrubby Alchemilla on well drained 
ground. 



102 Ruwenzori Expedition, 1952. Volume I, Number 6 

The single female, which is brachypterous, was beaten from a species of Galium festooning the 
trunk and lower boughs of a Philippia. The fore wings are tapered distally, pale orange yellow 
irrorate with orange buff; medial area broad and fuscous; some fuscous irroration in the basal 
and distal fourths; hind wing tapered distally, pale orange yellow with a fuscous medial fascia. 

Distribution : Ruwenzori. 

Xanthorhoe wellsi capnoessa subsp.n. (Figure 17) 

Differs from the nominate subspecies in the colour of the hind wing, which is a smoky buff 
instead of smoke grey; buff colour is in evidence on the costa of the fore wing also. The underside, 
especially distad of the medial area, is smoky buff instead of being uniformly fuscous. 

The single brachypterous female was found close to a resting male, crawling on a species of 
Galium festooning the trunk of an arborescent Senccio. The fore wing is tapered distally, light buff 
irrorate with fuscous and fuscous black; postmedial fascia slenderly black followed by a fascia of

The brachypterous female has the fore wing tapered distally; the basal, medial and terminal 
areas are fuscous black, the remainder of the wing is light buff lightly irrorate with fuscous 
black. Flind wing light buff with a broad, fuscous, medial fascia. 

It is possible that wellsi and bamsi will prove to be subspecies of heteromorpha, for they replace 
each other at different elevations. The genitalia of these three allopatric, day-flying species are 
identical and also identical with those of the sympatric night-flying alluandi. 

Xanthorhoe ablechra sp.n. (Figures 142-144) 
Calostigia vana Prout, 1926, Ark. Zool., 18A Number 25:6 (part). 

24-27 mm. : Male. Palpus, head, thorax and abdomen white to pale pinkish buff irrorate with 
cinnamon; posterior edge of each abdominal segment with a pair of fuscous spots. Wings white 
to pale pinkish buff, glossy; costa of fore wing lightly irrorate with cinnamon and with a little 
fuscous basad; cell spot minute, often wanting; hind wing immaculate. Underside pale pinkish 
buff lightly and evenly irrorate with snuff brown; cell spots and postmedial fasciae fuscous, faintly 
marked on both wings. In the female the fore wing is densely irrorate with cinnamon, especially 
distad of the conspicuously lunulate, white postmedial fascia. In vana Prout both sexes are a 
glossy, immaculate white. 

Male genitalia: Uncus slender and tapered, slightly shorter than the membranous, ventral 



Geometridae 103 

margin of the valve (ratio 13 : 15) ; in vana the uncus is still shorter (ratio 9:15). Dorsal margin of 
valve sclerotized, apex rounded, the whole rather broader than in vana. Apex of vesica with a 
cluster of four spines, equal in length to the width of the aedeagus; in vana there are two series of 
very short spines near the apex. 

Female genitalia: Genital plate triangular, sclerotized and ridged horizontally; two strongly 
sclerotized lobes, one at each side anteriorly; ductus bursae lightly sclerotized in posterior third, 
remainder membranous; bursa copulatrix membranous, without signa. Differs from vana in 
having the anterior half of the ductus bursae membranous and not sclerotized. 

The species is similar in colour to X. ruandana Debauche (1938) but is much smaller.

The female has the white fasciae bordering the medial area of the fore wing narrowed and the 
remainder of the wing suffused with ochraceous tawny to ochraceous orange. The male comes 
to light in very large numbers but all the females taken during the 1952 expedition were beaten

The female differs from the male in having a much less strikingly contrasted fore wing; the 
ground colour is vinaceous drab irrorate with fuscous ; the medial area is edged proximally and 
distally with a broad fascia of ochraceous tawny or chestnut. The glossy pearl grey medial area 
}f the hind wing in each sex makes the species readily recognizable. 

Distribution: Uganda, Virunga Mts. 'C. Africa', type locality; possibly W. side of Ruwenzori.

In specimens from Western Uganda the postmedial fascia on the fore wing is almost straight, 
as in the type series of leopoldi; in the only two specimens of t. transcissa Warren (1902) in the 
British Museum, the postmedial fascia is markedly incurved between veins Mi and M3 . Further 
material may show these differences to be merely individual, but for the present the two forms 
are better kept separate. 

One of the male specimens from Nyinabitaba matches ab. triangulata Debauche (1938).

In addition to the superficial differences between brachytoma and transjugata Prout, mentioned 
by Prout in his original description of brachytoma, there are differences in the structure of the 
male genitalia. In transjugata the process on the dorsal margin of the valve is equal in length to the 
width of the valve, extends to its apex and is twice as long as that of brachytoma. In transjugata 
the vesica bears three clusters of spines ; in brachytoma there is only one such cluster. 

Xanthorhoe oculata sp.n. (Figures 21, 145) 

9 32-36 mm.: Fore wing. Ground colour light buff to cinnamon; basal and medial areas and 
terminal area, except tornus, fuscous ; proximal margin of medial area right-angled on vein Cuz ; 
at mid-costa is a ring of the ground colour within the medial area, the cell streak at its posterior 
margin; fringes fuscous. Hind wing pale pinkish buff; termen and anal margin lightly irrorate 
with fuscous; anal margin with traces of the transverse fasciae marked in fuscous; cell spot 
minute; fringes warm buff divided by a fascia of fuscous. Underside of both wings glossy, light 
to warm buff very lightly irrorate with fuscous ; cell spots and lunulate postmedial fasciae clearly 
marked, fuscous; the fore wing, proximad of the postmedial fascia and posterior of the radius, 
is fuscous; fringes of both wings fuscous. 

Genitalia: Genital plate almost ovate, sclerotized. Ductus bursae and bursa copulatrix shaped 
as figured. 

Related to transcissa Warren (1902) and to brachytoma Prout (1933) but readily distinguishable 
from them by the shape of the medial area of the fore wing.

and abdomen tilleul buff irrorate with fuscous and very lightly with cinnamon rufous to chestnut. 
Fore wing cinnamon rufous, basal and medial areas chestnut; medial area edged proximally and 
distally with white and posteriorly, along the inner margin, with fuscous; subterminal fascia 
represented by white spots between the veins, that between M3 and Cm being large and con- 
spicuous. Hind wing tilleul buff suffused with fuscous ; in the distal third the veins and the anal 
area are cinnamon rufous to chestnut. On both wings the fringes are cinnamon rufous to chestnut 
proximally and chequered fuscous and tilleul buff distally. Underside of both wings tilleul buff 
densely suffused with cinnamon rufous to chestnut; proximal two-thirds of both wings, except 
costa of fore wing, irrorate with fuscous.

Mimoclystia eucesta sp.n. (Figures 22-24, 146, !5 2 > : 53) 

cT9 33—37 mm.: Male antenna lamellate and shortly cihate with a pair of bristles on each segment 
anteriorly; female antenna similar but almost filiform. Palpus twice as long as the diameter of 
the eye in each sex. Fore wing very variable in colour and pattern ; basal and terminal areas usually 
fuscous ; proximal margin of medial area usually indentate mediad along the subcostal vein and

wing acutely angled. Neuration as illustrated. 



no Rtiwenzori Expedition, 1952. Volume I, Number 6 

Male genitalia: Uncus slender and tapered. Saccus broadly rounded and not produced. Valve 
almost circular, simple. Anellus lobes semicircular. Subscaphium scobinate. Aedeagus rather 
longer than the valve, narrowed at one-third and again at two-thirds, tapered and sclerotized 
apically. Abdomen without coremata. Eighth tergite roughly triangular; eighth sternite bifurcate. 

Female genitalia: Genital plate shaped as illustrated. Ductus bursae cylindrical, slender and 
sclerotized medially, two-thirds as long as the diameter of the bursa copulatrix, which is globular 
and membranous with a single, scobinate signum. 

The simple valve and well developed anellus lobes are closely similar to those in Chloroclysta; 
the development of the sclerotized eighth sternite and tergite suggest a relationship with 
Eupithecia. 

Type species: Lareutia monticolata Aurivillius (1910). 

The gender of the generic name is feminine. 

The following species are included in addition to the type species : 

Lareutia sjostedti Aurivillius (1910) 
Tephrina inaequata Walker (1861) 
Perizoma eoaeqtiata Prout (1935) 

Haplolabida sjostedti altipeta (Prout) 

Lareutia altipeta Prout, 1921, Bull. Hill Mus., 1:142, Plate 18:6. 
ruwenzori : Namwamba Valley, 10,200 ft. (Jackson), 5 

Superficially s. altipeta differs from s. sjostedti Aurivillius (19 10) in having much less fuscous 
suffusion on both wings and having clear, white markings on the fore wing; the postmedial fascia 
is slightly dentate, not smooth as in the nominate subspecies, more deeply excised basad posterior 
of the cell area, resulting in the posterior third being more acutely inclined tornad. In the genitalia 
the uncus is longer in proportion to the valve in s. altipeta (ratio 2:4) than in s. sjostedti (ratio 
o - 9:3'2). In s. altipeta the juxta is narrowed at one-third and the apical third is tapered; in s. 
sjostedti the juxta is of uniform width in the basal two-thirds. 

Haplolabida monticolata diplodonta subsp.n. (Figures 30, 154-159) 

6*? 34—36 mm.: Rather smaller than ;//. monticolata Aurivillius (1910), which has a wing-span of 
37-41 mm. On the fore wing there is much less fuscous suffusion; the transverse fasciae proximad 
of the postmedial, which in in. monticolata are scarcely traceable, are clearly marked in white. The 
postmedial fascia is broader and the white ground colour is conspicuous in the terminal area. 
Fringes chequered black and white. The underside of the hind wing has a broad, double, white, 
postmedial fascia, which is wanting in the nominate subspecies. In the male genitalia the juxta in 
in. diplodonta is considerably broader basad than in m. monticolata; the aedeagus in m. diplodonta is

Geometridae 



in 



Piercia cognata sp.n. (Figures 160-163) 

Similar in size, pattern and colour to P. fumitacta Warren (1903), which is found throughout 
equatorial Africa from Kenya to Mt. Cameroon, but differing in the genitalia of both sexes. 

Male genitalia: Asymmetrical. Uncus broad, apex sharply tapered; in fumitacta the uncus is very 
slender. Gnathus not developed. Ventral margin of both valves folded and lightly sclerotized with 
a broad, blunt process arising medially ; in fumitacta the process is slenderly digitate. Dorsal margins 
of valve sclerotized and produced asymmetrically as illustrated; in fumitacta the costal projections 
are shorter, almost symmetrical and similar in shape to the right costa of cognata but with the 
dorsal tooth at each side more than twice as broad. Aedeagus right-angled medially, apex tapered 
and slightly scobinate; in fumitacta the aedeagus is shorter, stouter and right-angled just below the 
apex. Vesica with a single cornutus tapered basad, one-fifth as long as the aedeagus ; in fumitacta 
the single cornutus is tapered apicad and is one-seventh as long as the aedeagus. 

Female genitalia: Ductus bursae shaped as illustrated and strongly sclerotized; in fumitacta it is 
of almost even width, slightly narrowed posteriorly and two-thirds as broad as long. Bursa 
copulatrix globular and membranous with a single, scobinate signum; in fumitacta the bursa 
copulatrix is ovate.

Piercia kennedyi sp.n. (Figures 25, 165-168) 

o* 31-34 mm.; $ 26-32 mm.: Inner and upper surfaces of palpus warm buff, remainder warm 
sepia. Frons light elm green above, warm sepia below. Head light elm green. Collar warm buff 
mixed with warm sepia. Thorax light elm green mixed with warm sepia ; tips of tegulae and 
crest on metathorax warm sepia. Abdomen light elm green and warm sepia dorsally, warm buff 
and warm sepia laterally and ventraUy. Male. Fore wing light elm green, costa sometimes irrorate 
with ochraceous orange, transverse fasciae more or less densely irrorate with warm sepia; basal 
fascia edged distally and medial fascia edged both proximally and distally with white ; distal area 
lightly irrorate with warm sepia both distad and proximad of the subterminal fascia, which is 
j white, marked only between the veins; termen black between the veins; fringes chequered warm 
sepia and ochraceous orange; cell spot fuscous black. In some specimens the distal half of the 
medial area, between veins M3 and Cuz, is more or less ochraceous orange. Underside ochraceous 
orange, the proximal two-thirds posterior of the subcostal vein, suffused with drab ; remainder 
irrorate with drab. Hind wing glossy, light buff, variable; proximal half, posterior of the radius, 
more or less suffused with drab ; subterminal lunulate, of irregular width, drab ; sometimes the 
wing is immaculate ; fringes warm buff to ochraceous orange chequered with drab. Underside

similar. In the female the basal and medial areas of the fore wing are uniformly warm sepia; the 
hind wing is usually suffused with drab, except for a broad postmedial fascia of warm buff. 

Male genitalia : Uncus broad in basal half, tapered apicad. Gnathus not developed. Valves sym- 
metrical, partially membranous, apex narrowly rounded; costa produced beyond apex, bifurcate, 
the ventral arm the longer; basal five-sixths of ventral margin sclerotized. Aedeagus sigmoid; 
vesica with a slender band of short spines medially. 

Female genitalia: Posterior half of ductus bursae sclerotized at right side; anterior half wholly 
sclerotized. Bursa copulatrix shaped as illustrated, the posterior half sclerotized and partially 
scobinate, the anterior half membranous with a single, scobinate signum. 

The structure of both the male and female genitalia indicate a close relationship to P.fumitacta 
Warren (1903); the species may be distinguished at once, however, by its very large size. 

It is with pleasure that I name this fine species o( Piercia in honour of Professor W. Q. Kennedy, 
leader of the 1952 expedition.

Piercia suavata sp.n. (Figures 27, 169) 

§ 23-24 mm.: Frons, head and collar coloured as in the preceding species. Thorax light elm 
green irrorate with warm sepia, the tips of the tegulae light buff to drab ; metathorax crested as in 
P. kennedyi. Abdomen light buff irrorate with drab and warm sepia, less densely laterally. Fore 
wing of smooth appearance with a clearly defined medial area; ground colour light elm green, 
suffused with cinnamon in the paratype; basal fascia, best defined on costa, warm sepia; medial 
area dark elm green irrorate with drab or warm sepia, the proximal margin straight from the 
subcostal to the inner margin, the distal margin toothed on veins Mi and M3 and edged dis tally 
with white ; in the paratype the medial area is suffused with cinnamon between veins Mi and M3 
distad of the discocellulars ; an area of drab is situate at the costa midway between the distal edge 
of the medial area and the apex and another, arc-shaped, at the termen between veins Sc<, and 
M3 ; cell spot wanting. Underside warm buff, the sepia areas of the upperside suffused with 
drab beneath. Hind wing light buff proximad of the postmedial fascia, distad of it lightly irrorate 
with drab. Underside warm buff very hghtly irrorate with drab ; postmedial and subterminal 
fasciae slenderly drab. Fringes of both wings light buff and drab. 

Genitalia: Ductus bursae very short and sclerotized. Bursa copulatrix ovate and membranous; 
a hghtly sclerotized band is situate posteriorly and a scobinate signum medially. 

The evenly coloured, well contrasted and sharply defined medial area makes P. suavata a 
distinctive species in the genus; the genitalia (Figure 169), however, probably afford the most 
reliable means of identification.

Coenotephria spatiosata Walker Prout nee Walker, 1932, Mem. Soc. zool. Fx., 29:436. 

Similar in size, pattern and coloration to P. spatiosata Walker (1862), with which it has long 
been confused, but differing in the genitalia of both sexes. The areole in the fore wing is usually 
divided but occasionally it is undivided in both species. 

Male genitalia: Uncus broad and spatulate at base, tapering apicad; in spatiosata it is evenly 
rounded and tapered. Arms of gnathus very short and stout; in spatiosata these are not developed.

Eois rectifasciata sp.n. (Figures 38, 68) 

o* 20 mm.; $ 22 mm.: Closely related to E. innocens Warren (1902) (Figure 69) and to E. alticola 
Aurivillius (1925), differing in the colour and pattern of the wings and in the female genitalia. 
Both wings are light pinkish cinnamon; on the fore wing the slender, fuscous, postmedial 
fascia is straight between veins Sc$ and Cm ; in innocens and alticola the postmedial fascia is lunulate 
and incurved between these veins. On both wings the termen is marked with minute black dots 
between the veins ; in the related species these markings are extended so that the termen is fuscous, 
interrupted only at the veins. 

In the female genitalia the differences in the extent of the spining of the bursa copulatrix and 
in the size of the respective signa may be seen from the figures (Figures 68, 69). In alticola the 
sclerotized part of the ductus bursae is considerably extended, being three times as long as broad.

Xanthisthisa holmi sp.n. (Figures 41, 199, 200) 

o 71 47-49 mm.: Antenna bipectinate to three-fifths, the longest pectinations, which are at one- 
third, equal to ten times the diameter of the shaft. Terminal segment of palpus drab, remainder 
ochraceous buff. Frons cartridge buff. Head light buff irrorate with drab. Thorax warm buff 
Abdomen light buff. Fore wing light buff to pale ochraceous buff lightly irrorate with black ; 
a double fascia of ochraceous buff extends diagonally from apex to one-half inner margin; 
proximad of and parallel to this fascia is situate a band of black densely irrorate with light buff ; 
terminal area from vein Mi to tornus black densely irrorate with light buff. Underside ochraceous 
buff, distal third of costa and inner margin light buff, lightly irrorate with black ; a black fascia 
from apex extends diagonally to one-half inner margin, slender anteriorly, broadening posteriorly. 
Hind wing light buff shading to pale ochraceous buff distally, anal margin sparsely irrorate with 
black ; in some examples a diagonal fascia, faintly marked in a deep shade of buff, extends from 
apex to one-half anal margin. Fringes on both wings pale ochraceous buff. Underside light 
ochraceous buff sparsely irrorate with black; diagonal fascia as on upperside but more strongly 
marked. 

Genitalia: Uncus simple. Apex of gnathus trapezoid and spined, the spines decreasing in size 
mediad. Valve shaped as illustrated, the sclerotized dorsal margin tapered and very shortly 
produced ; process on basal half of ventral margin sclerotized and tapered, its apical half finely 
spined on inner edge. Aedeagus subequal to dorsal margin of valve, apex tapered and ringed with 
ten stout spines; vesica with a fan-shaped cluster of spines near apex. 

Related to X. tarsispina Warren (1901), differing superficially in the colour and pattern of the 
fore wing, the almost complete absence of pattern on the hind wing and the absence of cell spots 
on both wings and structurally in the shorter process on the ventral margin of the valve and the 
greater number of spines ringing the apex of the aedeagus.

Semiothisa phaeostigma sp.n. (Figures 52, 70, 202, 203, 209) 

o*§ 28-30 mm.: Cilia of male antenna rather longer than the diameter of the shaft; those of the 
female minute. Palpus in each sex one and one-half times as long as the diameter of the eye. 
Palpus, frons, head, thorax and abdomen drab. Fore wing v/ith distal margin incurved between 
veins Sc$ and M3, cinnamon drab; medial area with some cinnamon buff irroration distally 
along costa ; antemedial and medial fasciae poorly defined, snuft brown to fuscous ; a conspicuous 
fuscous patch, edged posteriorly with cinnamon buff and divided by a slender streak of the same 
colour, the streak inclined diagonally tornad, is situate at three-quarters costa; a second patch 
of fuscous black, edged proximally with cinnamon buff, is situate distad of the discocellulars 
between veins M2 and Cm; termen very slenderly fuscous; fringes slenderly cinnamon buff 
proximally, fuscous distally. Underside, posterior of the radius and vein Mi, uniformly drab; 
J costal area warm buff lightly irrorate with white, the transverse fasciae broadly marked by 
patches of ochraceous tawny; termen fuscous between veins Sc$ and M3. Hind wing, toothed at 
vein M3, almost uniformly drab; anal margin irrorate with cinnamon buff, on which the fuscous, 
transverse fasciae are poorly defined; cell spots on both wings small and fuscous; termen and 
fringes as on fore wing. Underside drab irrorate with white; medial fascia fuscous; postmedial 
fascia broad, fuscous anteriorly and posteriorly, ochraceous tawny medially. 

Male genitaha: Valve shaped as in illustration. Aedeagus sclerotized both dorsally and ventrally ; 
vesica with one tapered cornutus. Eighth sternum shallowly U-shaped. 

Female genitaha : Genital plate semicircular, little wider than the short, slender ductus bursae. 
iBursa copulatrix shaped as in illustration, sclerotized posteriorly and densely but weakly and

Xylopteryx phaeochyta sp.n. (Figures 54, 82, 212) 

^ 38 mm.: Antenna bifasciculate, each tuft of cilia almost twice as long as the diameter of the shaft 
(ratio 7:4). Palpus one and one-half times as long as the diameter of the eye. Hind tibia not dilate 
and without hair pencil. Palpus, frons and thorax light drab irrorate with fuscous. Head light 
buff. Abdomen pale ecru drab irrorate with black; first segment black on dorsum. Fore wing 
buffy olive irrorate with black, except at apex, tornus and terminad between veins M3 and Chi ; 
transverse fasciae very lightly irrorate with white; basal fascia broad and black; slender, dentate 
ante- and postmedial fasciae much broken, black; subterminal fascia broad, straight and black; an 
area of black between veins Mi and M3 extends from the subterminal fascia to the termen ; 
fringes chequered black and buffy olive; cell spot ringed with black. Hind wing, including fringes, 
pale pinkish buff, termen and anal margin Lightly irrorate with pinkish buff and black; cell spot 
black. Underside pale pinkish buff lightly irrorate with black; cell spots on both wings black; 
subterminal fascia and terminal area on fore wing between veins Mi and M3 black. 

Genitalia: Uncus broad and trilobate at apex. Gnathus slender. Valves asymmetrical, the sclcro- 
tized ventral margin of the left valve bearing a spined process at its tip. Aedeagus tapered and 
sclerotized in apical third with a minute, tooth-like projection just below apex. The vesica bears 
a cluster of four stout spines in basal third and a dense cluster of very slender spines medially, all 
greater in length than the width of the aedeagus. 

Readily distinguished from other species of Xylopteryx so far known by the pale, almost 
immaculate hind wing. X. sima Prout (1926) has a weakly marked hind wing but has also a dilate 
hind tibia with a hair pencil in the male.

Ectropis holmi sp.n. (Figures 45, 75, 213) 

(J 36-38 mm.: Closely similar in size, colour and pattern to the preceding species, with which it 
flies. Antenna bipectinate, the longest pectinations being a little longer than the diameter of the 
shaft (ratio 4:3); in ocellata Warren the pectinations are almost three times as long as the diameter 
of the shaft (ratio 8:3). Both the fore and hind wings are white, lightly irrorate with snuff brown 
and patterned with fuscous ; in ocellata the wings are densely irrorate with drab and snuff brown 
and patterned with snuff brown; holmi presents a cleaner and whiter appearance, having less 
dark irroration and a sharply contrasted pattern. 

Genitalia : Uncus broadly rounded at apex, densely spined dorsally. Valves shaped as illustrated, 
the ventral margin slenderly, the dorsal margin broadly sclerotized and spined; a small process 
bearing 10-12 stout spines arises medially. Apical third of aedeagus sclerotized and tapered; base 
narrowed and rounded. Vesica with one weakly sclerotized cornutus. In ocellata the apex of the 
uncus is concave ; the medial process on the valve is smaller and bears a very dense cluster of weak 
spines; the apical half of the aedeagus is flattened and sclerotized, the lateral margins being irregu- 
larly serrate; the vesica bears one stout cornutus, which is tapered apicad.

Ectropis elaphrodes sp.n. (Figures 46, 81) 

29-31 mm.: Similar in size, colour and pattern to E. anisa Prout (1915). The fore wing differs 
in having less snuff brown irroration proximad of the subterminal fascia. The hind wing differs 
in having the antemedial and double postmcdial fasciae extending from the radius to the anal 
margin; in anisa these fasciae are marked only as spots on the anal margin. 

Genitalia: Uncus broad-based and tapered to a rounded apex, which is spined dorsally; in

Neocleora herbuloti sp.n. (Figures 44, 85, 215) 

o* 36-42 mm.: Previously confused with N. tulbaghata Felder (1875), from which it may be dis- 
tinguished by genitalia and usually by pattern. Medial area on both wings white, lightly irrorate 
with snuff brown to fuscous ; proximad of the medial area both wings are uniformly fuscous ; 
distad of it, white more or less irrorate with snuff brown to fuscous, slightly paler at apex; cell 
spots white heavily ringed with snuff brown to fuscous. 



Geometridae 137 

Genitalia: Valve shaped as illustrated with two sclerotized processes on the ventral margin; 
one is short with a smoothly rounded apex and arises at one-third; the second arises from the 
sclerotized basal half of the ventral margin, extends parallel to the membranous apical half, 
almost to the apex, and is densely spined, presenting a comb-like appearance. Aedeagus with a 
narrowly roimded, sclerotized apex; vesica bears two short, tapered cornuti. 

N. tulbaghata is fully described and illustrated by Janse, 1932, Moths of S. Africa, 1 :268, Plate 
8 : 1, Figure 100.

15-17 mm.; $ 17-20 mm.: Palpus, frons, head, thorax, abdomen and upperside of wings 
cream colour to maize yellow lightly irrorate with ochraceous tawny. Fore wing : basal, ante- and 
postmedial fasciae represented by broad, fuscous spots at costa; medial fascia fuscous, straight 
from one-half costa to one-half inner margin, the anterior half rather broader ; subterminal fascia 
fuscous, toothed distally between veins Mi and M3 and forming a large fuscous spot extending 
to termen, otherwise straight from three-fourths costa to tornus, where there is a second large, 
fuscous spot; termen slenderly black. Underside buff yellow with a little fuscous irroration near 
base of wings in some examples; termen, medial and subterminal fasciae as on upperside. Hind 
wing with a large, fuscous spot at mid-costa, from which the slender, ochraceous tawny, medial 
fascia extends to one-half anal margin ; subterminal fascia, toothed to termen between veins Mi 
and M3, otherwise straight from apex to anal angle, very slender, ochraceous tawny; termen 
slenderly black. Underside buff yellow; medial and postmedial fasciae, the latter usually much 
broken, fuscous. 

Male genitalia: Uncus as broad as aedeagus, apex sharply narrowed. Juxta bifid, both arms 
slender with rounded apices, the left arm two-thirds as long as the right. Valve shaped as in 
illustration. Aedeagus short and straight. Vesica without cornuti. 

Female genitalia: Genital plate triangular, the posterior edge usually concave and dentate. 
Bursa copulatrix shaped as in illustration, the apex hghtly sclerotized, the remainder membranous 
with a signum situate medially. 

Differs from the closely related L. mouilifera Prout (1915) superficially in the paler colour of 
the wings, with their complete lack of fuscous irroration, the large, fuscous spots at mid-termen 
and tornus of the fore wing and at mid-costa of the hind wing. Differs structurally in the juxta 
of the male genitalia, which in mouilifera is also bifid and asymmetrical, the arms being short and 
stout, that on the left being angled inwards at 90 near apex; in the female genitalia of mouilifera 
the genital plate is differently shaped from that of pachyspila and the signum on the bursa copula- 
trix is minute and situate in the posterior third.

mon drab. Frons cinnamon drab. Vertex fuscous.Thorax and abdomen white. Fore wing white 
and glossy, very lightly irrorate with drab grey; pattern drab grey consisting of four ill-defined, 
transverse fasciae, which are straight and parallel to the termen ; the first is broad and extends from 
one-fourth costa to one-fourth inner margin; the second is slender and extends from one-half

in illustration, the posterior third sclerotized and ribbed, the remainder membranous with a 
stellate signum at the right side in the anterior third. 

Placed provisionally in the genus Lomographa because of affinities shown in the structure of 
the genitalia. Distinguished from other known species of African Ennominae by the glossy, 
white wings.

The neuration of the fore wing is variable; veins Ri and R2 may be connate or stalked; in 
several examples these veins are connate on one wing and stalked on the other; the wing-span 
ranges from 23-26 mm. Monsieur C. Herbulot has kindly compared the genitalia of the holo- 
type of pulvisaila with those of irisaria and found them to be conspecific.

valve, which is shaped as in the illustration. Ventral margin of valve bears a broad-based, sclero- 
tized process with an incurved, bifurcate apex. Aedeagus rather longer than valve, slender and 
almost straight. Vesica with a slender cornutus, one-half as long as the aedeagus. 

Female genitalia: Genital plate sclerotized and shaped as in the illustration with two pairs of 
lobes, a small pair posteriorly and a larger, incurved pair anteriorly; bursa copulatrix cylindrical 
and membranous with a weakly sclerotized signum at the right side in the anterior half. 

Similar in pattern to O. bisecta Warren (1904) but rather larger. Differs structurally in the 
genitalia of both sexes, the male of that species having a tapered, falcate process on the valve, with 
a short projection medially and a short, stout, unadorned aedeagus; the female lacks the complex 
ornamentation of the genital plate.
